Abstract

PCT No. PCT/CH96/00128 Sec. 371 Date Oct. 14, 1997 Sec. 102(e) Date Oct. 14, 1997 PCT Filed Apr. 11, 1996 PCT Pub. No. WO96/32755 PCT Pub. Date Oct. 17, 1996Antenna system including a first antenna which is connected to a first transmit and/or receive unit and which has a natural frequency of at least approximately the value fm. The system also includes a second antenna which is linked both inductively and mechanically to the first antenna and which has a natural frequency of at least approximately the value fm. The first and second antennae are designed to be linked to another antenna system with at least a third antenna which has a natural frequency of at least approximately the value fm and which is connected to a second transmit and/or receive unit intended for the transmission of data to and/or reception of data from the first transmit and/or receive unit. At least one transmit and/or receive unit, either of the first or the second transmit and/or receive unit, is located at a route point on a public thoroughfare. The other transmit and/or receive unit is located on a vehicle driving on the public thoroughfare. The antenna system proposed enables a broad-band transmission channel to be made available with only low attenuation.
